FIA says Halo saved LeClerc at Spa

Alonso sails over Leclerc

The FIA believes IndyCar's inferior 'aeroscreen' concept would have been only 10% as effective as Formula 1's halo in protecting Charles Leclerc in the Belgian Grand Prix start crash.

The official investigation into the Spa accident, which was caused when Fernando Alonso was tipped over the top of Leclerc's Sauber by a late-braking Nico Hulkenberg at the first corner, has concluded that the halo played a crucial role in preventing injuries.

The halo withstood the 58kN strike that it took from Fernando Alonso's right-front wheel, and analysis showed it deflected the car away from striking Leclerc's helmet.
